IGN - We all know Call of Duty: Modern Warfare 3 is coming. In development at Infinity Ward with assistance from Activision studio mates Raven and Sledgehammer Games. We don't know much about it, but like pretty much all big game sequels, we talk all the time at the IGN offices about what we want to see next - and what we hope fails to make a return appearance. But we're also interested in what our readers have to say, because hey, we're here for you. With that in mind, we went to Twitter with a simple question: what do you want to see in Call of Duty: Modern Warfare 3?
